How the Internet is rewiring our brains
Nicholas Carr with Gideon Haigh
"Like lab rats pressing a lever," when referring to the way technology facilitates our craving for new information so much that we will disregard what we are currently concentrating (already procured) on to replace it with something new.
- Throughout, Carr does a good job of basing the cases he attempts to make on how the brain functions.
- Video games: Part I at the ~10 min mark.
- 20:35 Adding links to text decreases comprehension b/c it activates decision making in the brain, reducing working memory that can be allocated to focusing on comprehending the text.
- Pt. 2 Danger in our tendency to start thinking of the Web as a replacement to our long term memory (LTM) instead of a supplement. "I don't have to remember that because I can just remember the search string."
- Pt. 2 a 3:10, claims Google (and other search engines) are dangerous because they serve up fragments and "return the most popular stuff instead of perhaps the best stuff" and everyone gets the same thing. I disgree with problems on the fragments... for me, fragments are like hand-holds on a cliff, or clues. Oftentimes when doing research, especially in new areas where one doesn't have a developed understanding of the domain, one doesn't even have the language for asking questions, thus the fragments and having something like Google to help guess what I mean is of enormous help. The danger is stopping there, which I see many students do on campus.
- Pt. 2 at 8:40 - putting journals online has hurt scholarship. Mixed feelings about this. I am working on a lit review right now, and I am so very thankful for the electronic PDFs and ability to search databases, but Carr says having them online has narrowed the scope of research instead of broadening it as people thought it would.
